Changes to the 2021 International Building Code allow for construction of mass timber buildings with larger heights and areas than is currently permitted in Types III, IV, and V construction. This presentation will provide an overview of the allowable heights and areas for the three new types of mass timber construction: Types IV-A, IV-B, and IV-C. Construction fire safety requirements and owner responsibilities related to the fire resistance elements of the building will also be discussed.

Learning Objectives:

1. Describe the development process for allowable heights, areas, and number of stories permitted for tall mass timber types of construction
2. Evaluate the new fire barrier requirements
3. Recognize provisions for construction site fire prevention
4. Recite the owner responsibilities for fire resistance elements
